今天,我们将深入了解如何使用 Python 的 playwright.async_api 来进行异步浏览器自动化。 一、什么是 Playwright? Playwright 是由 Microsoft 开发的一个开源自动化框架,支持多个浏览器(包括 Chromium、Firefox 和WebKit)。它不仅可以用于自动化测试,还可以用于数据抓取、网站监控等任务。 二、安装 Playwright 在开始之前...
1. Python Playwright 概念 Playwright 是一个由 Microsoft 开发的开源自动化框架,支持多个浏览器(包括 Chromium、Firefox 和 WebKit)。它不仅可以用于自动化测试,还可以用于数据抓取、网站监控等任务。Playwright 提供了丰富的 API,使得开发者可以方便地编写自动化脚本。 2. 异步(Async)在 Python 中的含义和用途 在Py...
首先,我们需要安装Playwright库,可以通过以下命令来安装: pipinstallplaywright 1. 导入sync_playwright和async_playwright 在Python文件中导入sync_playwright和async_playwright: fromplaywright.sync_apiimportsync_playwrightfromplaywright.async_apiimportasync_playwright 1. 2. 创建sync_playwright和async_playwright实例 使用...
Playwright使用异步方法的正确姿势 如下代码会正常运行,通过await可以保证脚本的运行顺序 复制 async def playwright_async_demo(): asyncwithasync_playwright()asp: browser=await p.chromium.launch(channel="chrome")page=await browser.new_page()await page.goto("http://www.baidu.com")asyncio.run(playwright_...

Python Playwright async exampleMany libraries have support for asynchronous programming. The MS Playwright library allows to automate browsers both in synchronous and asynchronous modes. screenshot.py #!/usr/bin/python import asyncio from playwright.async_api import async_playwright async def main(): ...
import threading from playwright.async_api import async_playwright from concurrent.futures import ThreadPoolExecutor, ProcessPoolExecutor class Tls(threading.local): def __init__(self) -> None: self.playwright = async_playwright().start() print("Create playwright instance in Thread", threading.curre...
为提高效率与增加逼格,墙裂建议引入async异步编程,这不比基于threading的线程、基于multiprocessing的进程香?这些大家伙太重量级了,代码又啰里啰唆的一点也不pythonic,只有gevent协程能与之一战了,但async家族是python原生态的,故强烈建议采用async家族的异步来做异步编程。
